		Helper tool to access and edit [Mesh] data.
	</brief_description>
	<description>
		The MeshDataTool provides access to individual vertices in a [Mesh]. It allows users to read and edit vertex data of meshes. It also creates an array of faces and edges.
		To use the MeshDataTool, load a mesh with [method create_from_surface]. When you are finished editing the data commit the data to a mesh with [method commit_to_surface].
		Below is an example of how the MeshDataTool may be used.
		[codeblock]
		var mdt = MeshDataTool.new()
		mdt.create_from_surface(mesh, 0)
		for i in range(mdt.get_vertex_count()):
		    var vertex = mdt.get_vertex(i)
		    ...
		    mdt.set_vertex(i, vertex)
		mesh.surface_remove(0)
		mdt.commit_to_surface(mesh)
		[/codeblock]
